RemoveAllImageReferences Method (original) (raw)
Summary
Removes all the referenced images from the "Referenced Image Sequence" in all Graphic Annotation Sequence items.
Syntax
public void RemoveAllImageReferences() public:
void RemoveAllImageReferences();
Example
using Leadtools;
using Leadtools.Dicom;
public void GraphicAnnSequenceSample()
{
//Make sure to initialize the DICOM engine, this needs to be done only once
//In the whole application
DicomEngine.Startup();
using (DicomDataSet dicomDataset = new DicomDataSet())
{
// We can also initialize in here the "Grayscale Softcopy Presentation State" class
dicomDataset.Initialize(DicomClassType.Undefined, DicomDataSetInitializeType.ExplicitVRLittleEndian);
dicomDataset.CreateGraphicAnnSQItem(0, "Layer0");
DicomElement firstGraphicAnnSQItem = dicomDataset.FindFirstGraphicAnnSQItem();
Debug.Assert(firstGraphicAnnSQItem != null);
//If there was more than one item we can use
//FindNextGraphicAnnSQItem to enumerate these items
dicomDataset.SetLayerName(firstGraphicAnnSQItem, "Layer1");
Debug.Assert(dicomDataset.GetLayerName(firstGraphicAnnSQItem) == "Layer1");
// We can also call RemoveAllImageRefFromAllLayers or call
// RemoveImageRefFromLayer to remove the referenced images one by one.
// In any case this is for demonstration purposes only, since the dataset
// doesn't have any referenced images right now.
dicomDataset.RemoveAllImageReferencesFromLayer(firstGraphicAnnSQItem);

// 1.2.840.114257.3.6.5.5.18900282
